<div class="block">Encodes a string into a NYSIIS value. NYSIIS is an encoding used to relate similar names, but can also be used as a

 NYSIIS features an accuracy increase of 2.7% over the traditional Soundex algorithm.

 Algorithm description:
 <pre>
 1. Transcode first characters of name
   1a. MAC -&gt;   MCC
   1b. KN  -&gt;   NN
   1c. K   -&gt;   C
   1d. PH  -&gt;   FF
   1e. PF  -&gt;   FF
   1f. SCH -&gt;   SSS
 2. Transcode last characters of name
   2a. EE, IE          -&gt;   Y
   2b. DT,RT,RD,NT,ND  -&gt;   D
 3. First character of key = first character of name
 4. Transcode remaining characters by following these rules, incrementing by one character each time
   4a. EV  -&gt;   AF  else A,E,I,O,U -&gt; A
   4b. Q   -&gt;   G
   4c. Z   -&gt;   S
   4d. M   -&gt;   N
   4e. KN  -&gt;   N   else K -&gt; C
   4f. SCH -&gt;   SSS
   4g. PH  -&gt;   FF
   4h. H   -&gt;   If previous or next is nonvowel, previous
   4i. W   -&gt;   If previous is vowel, previous
   4j. Add current to key if current != last key character
 5. If last character is S, remove it
 6. If last characters are AY, replace with Y
 7. If last character is A, remove it
 8. Collapse all strings of repeated characters
 9. Add original first character of name as first character of key
